Although this is not necessarily related to your issue, you might want to consider creating an open() and close() for your DB and use a SQLiteOpenHelper object in each - in open(), you would use sqliteopenhelperObj.getWriteableDatabase() and in close() you would use sqliteopenhelperObj.close().

4. If you've downloaded files to your device during the process of testing an app, and you want to delete them, you can use the Device Monitor in Android Studio https://developer.android.com/tools/help/monitor.html There's a file manager that will allow you to see and edit files on your devices. You can also do this on the command line with the ADB (Android Debug Bridge) https://developer.android.com/tools/help/adb.html
